[Ifeffit] Unable to use 64-bit Demeter on Windows computer

Hello, I am just sending this email to see if anyone has encountered the following problem: I downloaded the newest 64-bit version of Demeter on my Windows computer, and it downloaded successfully, but now when I double click on the program, a tiny window pops up for about 0.5 seconds and then disappears. I have tried redownloading twice. Thank you very much, Brittaney -- *Brittaney Courchesne, G.I.T.* MSc Geology Candidate Harquail School of Earth Sciences Laurentian University Sudbury, ON *bcourchesne@laurentian.ca *
